Teknāf, Bangladesh

With a population of 333,865, Teknāf is hardly the tranquil coastal getaway it's marketed as. The bureaucratic headaches alone are enough to dissuade all but the most determined expats. And the tropical climate, while warm, brings punishing monsoons that can wreak havoc on infrastructure.

Safety is also a persistent concern, given Teknāf's location bordering Myanmar. While the literacy rate of 64.35% isn't terrible, it still lags behind the national average. This sleepy town is best suited for those with a high tolerance for red tape and a love of humidity - everyone else would do well to look elsewhere.
